10 The pulley with mass m = 3 kg and radius of gyration KG= 30 mm 0.045 m consists of two parts that are rigidly connected. Blocks A and B are of equal mass, mA = MB = 2 kg. At t=0, WO=0 w, a a) Sketch the free body diagram of the pulley. b) Write the compatibility equations between @, SA and SB c) Determine the angular acceleration of the pulley at 1=0, a(t=0). d) Determine the rotational kinetic energy of the pulley SB when A has moved a distance of 0.2 m. e) Determine the total kinetic energy of the system when A has moved a distance of 0.2 m. B Vakipyora, jonka massa on m = 3 kg ja hitaussade KG= 0.045 m, koostuu kahdesta osasta, jotka ovat jaykasti kiinni A Is, toisissaan. Punnuksilla A ja B on sama massa, mA = MB = 2 kg. Hetkella t=0 patee, wo=0. a) Piirra vakipyoran vapaakappalekuva. b) Kirjoita lauseke kulmanopeuden @, ja koordinaattien SA Seka SB Valille. c) Maarita vakipyoran kulmakiindyvyys hetkella t=0, a (t=0). d) Maarita vakipyoran rotaatioenergia, kun A on liikkunut matkan 0.2 m. e) Maarita systeemin kokonaisliike-energia, kun A on liikkunut matkan 0.2 m
